08 Apr SI Joint Exercises for Pain Relief and Stability

Author: Dr. Dave, Windy Ridge Chiropractic

SI joint pain can be frustrating because it often feels like something is simply “tight.”

You may feel pain on one side of your low back, near the top of your buttock, around the back of the pelvis, or during movements such as getting out of a chair, rolling over in bed, walking uphill, squatting, or hinging.

The natural response is often:

“I need to stretch this.”

Sometimes that is true. But not always.

One of the most important things to understand about SI joint pain is that mobility and stability are different problems. An irritated SI joint may need better movement. It may need better stability. Or it may need some combination of both.

That is why we do not recommend aggressively stretching every SI joint simply because the area feels tight.

What Is the SI Joint?

You have two sacroiliac—or SI—joints. They sit where the sacrum at the base of your spine meets the pelvis.

These joints do not move through large ranges like your shoulder or hip. Instead, they help transfer force between your trunk and legs while providing stability through the pelvis.

That becomes important when you walk, run, climb, lift, squat, hinge, carry, ski, or change direction.

The SI joints are part of the system transferring force from one half of your body to the other. When the joint itself or its supporting tissues become irritated, normal everyday movement can suddenly become uncomfortable.

If you are trying to understand whether your symptoms are coming from the SI joint, low back, hip, or another structure, our article on chiropractic care for lower back pain gives a broader overview of how we evaluate low-back and pelvic pain patterns.

What Does SI Joint Pain Feel Like?

SI-related pain commonly presents as one-sided low-back pain, pain near the “dimple” area at the back of the pelvis, buttock pain, pain when transitioning from sitting to standing, discomfort when rolling over in bed, or pain with walking, climbing, squatting, hinging, or loading one leg more than the other.

That does not mean every case of one-sided low-back pain comes from the SI joint. Muscles, lumbar joints, discs, nerves, hips, and other structures can create overlapping symptoms.

That is one reason an examination matters when symptoms persist.

Why Does an SI Joint Get Irritated?

Sometimes there is a clear injury. You slip, fall, twist, lift something awkwardly, or land poorly.

But just like many other mechanical low-back problems, SI irritation often develops without one dramatic event. Instead, repeated loading can gradually exceed what the area is currently prepared to tolerate.

That might happen after a sudden increase in running mileage, a hard ski weekend, returning to lifting after time off, repetitive bending or carrying, long periods of sitting, extensive driving, pregnancy or postpartum changes, a change in training volume, repetitive work, or reduced hip and trunk control.

In those situations, we are usually interested in more than just the painful joint. We want to know why that area is taking more stress than it can currently handle.

If prolonged sitting is part of the pattern, read our article on why sitting too long can contribute to low-back pain.

Tight Does Not Automatically Mean You Need to Stretch

This is the biggest change we would make to the way SI pain is commonly discussed online.

Painful areas often feel tight. Muscles around an irritated joint may guard. Your hips may feel stiff. You may feel like you constantly want to stretch or “pop” the area.

But the feeling of tightness does not tell us whether the problem is actually a lack of mobility.

Sometimes the body creates muscular tension because it is trying to protect an irritated area. And if the SI joint or its supporting ligaments are already irritated or lacking stability, repeatedly pulling on the area can sometimes make it feel worse rather than better.

Mobility and stability are not the same thing.

A mobility problem means the surrounding joints or tissues are not moving as well as they should. A stability problem means the body is not controlling movement or transferring force through the area as well as it should.

You can also have both at the same time.

The important point is simple: do not automatically stretch something simply because it feels tight.

So Should You Stretch an Irritated SI Joint?

Sometimes.

Gentle stretching can be useful when surrounding muscles or joints genuinely lack mobility and the movement feels comfortable. That may include gentle mobility work for the hip flexors, glutes, hamstrings, or hip rotators.

But stretching should feel like a comfortable mobility exercise, not an attempt to force the SI joint into submission.

If stretching causes sharp pain, makes the area feel less stable, significantly increases pain afterward, or repeatedly recreates the same SI symptoms, stop forcing it.

That may be a sign that mobility is not the primary thing the area needs.

Start With Movement

For most uncomplicated mechanical SI presentations, we generally prefer some movement to complete rest.

Walking is a great place to start. You do not need a workout. Short, comfortable walks throughout the day can help keep the hips, pelvis, and low back moving without placing a large amount of load on the area.

Also try to avoid remaining in one position for long periods. If sitting aggravates the area, change positions frequently.

Sit → stand → walk → sit.

The goal is not perfect posture. The goal is avoiding hours of uninterrupted loading in the same position.

This same idea shows up in our article on posture fatigue and why your body was not designed to stay still.

Stability Exercises for SI Joint Pain

Once the area tolerates movement, we often become interested in how well the trunk, hips, and glutes control the pelvis.

The following exercises can be useful for some SI presentations. They are not a substitute for an individualized examination, and they should not cause significant pain.

1. Glute Bridge

The bridge is a simple way to begin loading the glutes while keeping the movement controlled.

Lie on your back with your knees bent and feet on the floor. Brace your trunk gently, squeeze your glutes, and lift your hips until your shoulders, hips, and knees form roughly a straight line. Keep the pelvis level, then lower slowly.

Start with a comfortable number of repetitions rather than training to fatigue.

What we are looking for is both hips rising evenly, no sharp SI pain, glutes doing most of the work, and good control rather than maximum height.

2. Bird Dog

Bird dogs help train trunk and pelvic control while the arms and legs move.

Start on your hands and knees. Gently brace your abdomen, keep your pelvis level, and extend one leg behind you without rotating your trunk. Return slowly.

If that feels comfortable, progress to extending the opposite arm and leg together.

The goal is not to see how high you can lift the leg. The goal is to keep the trunk and pelvis controlled while the limb moves.

3. Abdominal Brace

This is intentionally simple.

Lie on your back with your knees bent, or perform it standing. Gently tighten the abdominal wall as though you were preparing for someone to bump into you. Continue breathing normally, hold briefly, then relax and repeat.

You should not be sucking your stomach in as hard as possible or holding your breath. We are teaching the trunk to provide support while you continue to move and breathe.

For more trunk-control ideas, read our article on core exercises that are not sit-ups.

4. Controlled Marching

Once basic bracing is comfortable, add movement.

Lie on your back with both knees bent. Gently brace your trunk, lift one foot a few inches from the floor, lower it slowly, and alternate sides.

Keep the pelvis from rocking side to side. This begins teaching the pelvis to stay controlled while the legs move independently.

5. Side-Lying Hip Abduction or Clamshell

The muscles on the outside of the hip contribute to pelvic control during walking, running, and single-leg activity.

For a clamshell, lie on your side with your knees bent. Keep your feet together, lift the top knee without rolling your pelvis backward, then lower slowly.

For side-lying hip abduction, lie on your side with the top leg straight. Keep the pelvis stacked, lift the leg without rotating backward, then lower with control.

Again, the goal is controlled muscular work, not chasing fatigue.

What About Squats and Deadlifts?

We do not consider squats, deadlifts, or hinge movements inherently bad for the SI joint.

In fact, those patterns are part of normal life and can be important components of rebuilding strength. But timing matters.

If the SI joint is acutely irritated or we see poor lumbopelvic stability, we may temporarily reduce heavy squatting, deadlifting, loaded hinging, asymmetric heavy loading, or high-volume repetitive bending.

That is usually a temporary modification, not a permanent ban.

The progression might look something like this:

Walking → basic stability → controlled bodyweight movement → light resistance → normal training.

The goal is to gradually restore the area’s ability to tolerate load.

For a deeper strength progression, read our article on building a stronger spine and hips with posterior chain work.

Do Not Confuse Avoidance With Recovery

There are two extremes we try to avoid.

One is: “It hurts, so I am going to stretch it harder and keep testing it.”

The other is: “It hurts, so I am never going to bend, squat, lift, or exercise again.”

Neither is particularly useful.

We want enough activity to keep you moving while temporarily reducing the specific loads that are clearly aggravating the problem.

Then we rebuild.

Heat or Ice?

Either can be reasonable for symptom relief.

Some patients prefer heat. Some prefer ice. Some like alternating the two. Use whichever helps you feel comfortable enough to continue moving.

Neither is the main solution. Think of heat and ice as comfort tools while the underlying problem recovers.

What About an SI Belt?

Some people with SI instability or irritation feel more comfortable with temporary external support such as an SI belt.

We view that as a tool, not a long-term substitute for strength and control.

If external compression clearly makes walking and normal activity more comfortable, it may be useful temporarily. But ultimately, we want the muscles around the pelvis and trunk doing the stabilizing work.

When Should You Get SI Pain Evaluated?

Consider getting examined if pain is not improving, the same problem repeatedly returns, you are unsure whether stretching helps or hurts, normal walking is difficult, you cannot return to exercise, squatting or hinging repeatedly causes pain, the pelvis feels unstable or unreliable, symptoms extend significantly down the leg, or you develop numbness, tingling, or weakness.

Those last symptoms are especially important because they may indicate that something other than—or in addition to—the SI joint is involved.

When SI Pain Might Not Be SI Pain

The location of pain is only part of the diagnosis.

Low-back, buttock, and pelvic pain can also come from lumbar muscle strain, lumbosacral ligament irritation, lumbar joint dysfunction, disc irritation, nerve involvement, hip problems, or other musculoskeletal and medical conditions.

That is why we do not diagnose an SI problem solely because somebody points to the back of their pelvis.

We look at the entire presentation.

What We Look for During an SI Joint Examination

Depending on the patient, we may evaluate where the pain is located, which movements reproduce it, lumbar and pelvic joint motion, SI joint provocation testing, hip mobility, glute strength, trunk stability, single-leg control, squat and hinge mechanics, and neurological function when indicated.

The goal is to answer a more useful question than:

“Is my SI joint out?”

We want to know what is irritated, what is not moving appropriately, what is not controlling movement appropriately, and what load the area is currently struggling to tolerate.

How Chiropractic Treatment Can Fit In

When SI-related pain is mechanical, treatment may include several different tools depending on the examination.

When appropriate, chiropractic manipulation can help improve motion in restricted lumbar, pelvic, or related joints.

Muscular guarding around the hips, glutes, and low back may respond to manual soft-tissue work, massage, cupping, or other techniques.

If poor stability or load tolerance is contributing, exercises for the glutes, hips, and trunk become an important part of the plan.

Sometimes the most useful change is temporarily reducing the specific movement or training load that repeatedly irritates the area. Then we gradually restore it.

The Bottom Line

If your SI joint hurts, do not automatically assume you need to stretch it.

Start with the bigger question:

Does this area need more mobility—or more stability?

For many patients, the best early approach is to keep moving, walk regularly, change positions frequently, avoid repeatedly aggravating the area, use stretching only when it actually feels helpful, begin controlled trunk and hip stability work when tolerated, temporarily modify heavy squat or hinge loading when needed, and progress gradually back toward normal activity.

The goal is not simply to make the painful area feel loose. The goal is to make your pelvis strong, controlled, and capable of handling the things you want to do.

If you are not sure whether your SI pain is a mobility problem, stability problem, or something else entirely, that is exactly what an examination is designed to determine.
